Carl,
I have my overflow going into an aluminium container, (in fact a 'Baroca
tube' the ones you can buy at the pharmacy or supermarket to boost your
life!) and is located on the pilot wheelwell firewall lower then the oil
tank (Classic). It normally has little in it at 100hr checks.
Cheers,
Tim

Subject: Europa-List: Oil tank venting
When we originally installed our oil tank (5 years ago) the vent line
was routed to the side of the cowling. The end result is that there is a
smell of oil coming in from the NACA vent when the aircraft is climbing.
I suspect the location of the outlet pipe is also in the airstream
resulting in an excessive loss of oil as it is getting sucked out (and
coating the side of the fuselage).
I was under the impression was that the solution would be to route the
vent pipe via a collector bottle but reading the manual Europa recommend
just routing it to the bottom of the cowling (the bottle being
optional).
My concern over the bottle arrangement is how long it takes to fill up
the overflow bottle with oil and how frequently one would need to remove
the cowling (to empty the bottle).
So, based on communal experience which is likely to be the best
arrangement - routing via the bottle or omitting the bottle and ensuring
the outlet isnt placed in the airflow where it could be sucked out.
One thought was to terminate the line at the exit of the exhaust stub
(using copper tube) which would hopefully vaporise and burn off any oil
that escaped. The arrangement would need to ensure no suction took place
- perhaps terminating using a T piece.
Suggestions please ?
